Ceratodon Nova-Granatensis Hpe. Mapiri, 5000 ft. (3107)= 

 Lindig, Nova Granada, Boq. Tequedamas, 1863. 



Leptodontium gracilescens C. MLiller. Yungas, 6000 ft. (3108) ;

 "Affine L. luteo foliis tamen patulis baud appressis or minus 

 longe cuspidatis differt." 



At Kew in Herb. Hooker there are four specimens of Jame- 

 son's from the Andes of Quito, labelled DidyuiodoTi liiteum, evi- 

 dently the types of Hook. Lond. Journ. 5 : 48. No. 174 is anno- 

 tated by Wilson : " var. foliis magis recurvis patenti-recurvo ser- 

 rulato." A part of 143 has the leaves much recurved as in 193b, 

 both of which are sterile. On the same sheet is a specimen of G. 

 Mandon's Plantae Andium Boliviensium Exsicc, no 1616, from 

 vicinius Sorata labelled Didymodon luteits Taylor, which quite 

 agrees with Rusby's specimens in its bright yellow recurved 

 leaves, longer pedicels two or three in the same perichetium, and 

 capsules twice longer than Jameson's specimen's. 



Leptodontium gracile C. Miiller, n. sp. Mapiri, 5000 ft (311 Ov 



Unduavi, 8000 ft. (3109). 



Plants bright yellowish green, stems slender, leaves squarrose 

 and curled when dry; cells densely papillose and obscure above, 

 clearer and oblong below, margins entire and recurved to above 

 the middle, sharply and doubly serrate above. Plants all sterile. 



Allied to Didymodon cinifoUus Hpe. by its papillose leaves but 

 with the aspect of L. gracilescens Miill. " Affine L. luteo foliis 

 longioribus quam L. gmcilescenta acutioribus margine non repetito 

 denticulatis." E. Bescherelle, teste. 



Leptodontium grimmioides C. Miiller, n. sp. Sorata, 13000 ft. 



(3192). 



Plants dark and discolored below, tips of the branches bright 

 yellowish green, stems 3-4 crn. long, leaves squarrose, spreading 

 and curled when dry, remaining undulate when moist, margins 

 entire and recurved below with a few protruding teeth above, vein 

 generally excurrent into a cuspidate apex, cells clear but papillose 

 at base, densely and finely papillose above. Plants sterile.
